The track drains very well, the only feature that might have been an issue has been avoided in the layout.
The car parking area "might" get a little muddy BUT should NOT be a problem so long as people drive sensibly (no big wheel-spins else you can dig yourself out
).
I personally see that there is no reason to cancel this meeting BUT if it does need to be I am sure Nathan will let us know.
Might take a spin out there tomorrow evening and have a look if Nathan can't do this.
